JOHN HUNTER CASSIDY, OF SAULT STE. MARIE, ONTARIO, CANADA.

RAIL-BENDING- MACHINE.

To all whom it may concern:

Be it known that I, JOHN HUNTER Cas- SIDY, of the town of Sault Ste.Marie, in the district of Algoma, in the Province of Ontario, Canada,have invented certain new and useful Improvements in Rail-BendingMachines, of which the following is the specification.

My invention relates to improvements in rail bending machines and theobject of the invention is to devise a simple form of machine which willbend a rail to'any desired curve as it passes over the track layingmachine to its place of deposit, and it consists essentially of a pairof vertically disposed rollers designed to bear against one side of therail and an adjustable roller designed to be forced against the oppositeside of the rail at a point between the aforesaid rollers so as to givethe desired bend to the rail, and means for driving the rollers so as togradually feed the rail through the machine as hereinafter moreparticularly eX- plained by the following specification.

Figure 1, is a general perspective view of my machine. Fig. 2, is alongitudinal section. Fig. 3, is a cross section.

In the drawings like letters of reference indicate corresponding partsin each figure.

A is the main frame of the machine supported upon a suitable portion ofthe track laying machine (not shown).

B are rollers journaled on shafts B and on which are mounted the gearpinions B B are journal brackets secured to the main frame A and B arevertical shafts j ournaled therein.

B are bevel gears secured to the top of the shaft B.

B are bevel gears secured to the bottom of the shaft B and meshing withthe bevel gear B C are cross shafts upon which are mounted bevel gears Cmeshing with the bevel gears B.

D are gear wheels mounted on each end of the shaft C.

E is a supplemental shaft mounted in bearings E and on which are mountedpinions E E are crank arms secured to the end of the shaft E.

F are suitably operated cylinders and pistons, the piston rods F ofwhich are connected to the cross heads F 2 connected by links F to thecrank arms E By this Specification of Letters Patent.

Application flied July 14, 1911.

means when the pistons of the cylinder F are reciprocated they rotatethe shaft E and through the pinions E and gear D drive the shaft C andalso the shaft B by means of the bevel gears C, B, B and B G areintermediate gears mounted upon suitable studs and serving to drive thegear wheels D from the gear wheels D. The gear wheels D drive a roller Dsimilar to the roller B and through a similar driving connection.

H are vertical rollers mounted upon the shaft B on one side of themachine and H are vertical rollers mounted upon the shaft B on theopposite side of the machine.

I is an adjustable roller mounted upon a vertical shaft I journaled inslide blocks I and I The slide blocks I and I are mounted upon crossguide-ways J and J.

K and K are threaded shafts extending through the blocks I and I andoperated in unison by means of the operating lever L mounted upon thestud L.

M is a sleeve surrounding the stud L to which is secured the ratchet Mand to the opposite end of which is secured the gear wheel L meshingwith the gears L and L on the shafts K and K respectively. The lever Lis also provided with a dog L engaging with the ratchet wheel M.

It will thus be seen that by operating the lever L the threaded spindlesK and K may be rotated so as to adjust the blocks I and I and the rollerI supported thereby to any desired position against the side of the railso as to force the rail into the required curve. The rail is then passedthrough the machine so as to curve the rail equally from end to end. Ofcourse, it will be understood that if it is desired to give a right orleft hand curve to the rail all that it is necessary to do is to eitherinsert the rail between the adjustable roller I and the rollers H or theadjustable roller I and the rollers H according to the directionof thedesired curve.

What I claim as my invention is.

In a rail bending machine, the combination with the main frame connectedintermediately of its length by upper and lower cross projectingguide-ways, and a block held between each of the upper and lowerprojecting guide-ways, of a vertical spindle journaled between the saidguiding blocks, a roller mounted thereon and designed to bear againstone side of the rail, threaded spindles journaled to the main frame andextending through the projecting guideways and threaded through. theblocks, an operating ratchet and lever, suitable gears connecting theratchet and lever to said spindles so as to operate the threadedspindles in unison, a rail supporting roller journaled in, the mainframe to the front and rear of the aforesaid roller, suitably journaledvertical spindles also located to the front and rear of the aforesaidroller, and rollers journaled thereon designed to bear against theopposite side of the aforesaid rail, and means for driving thesupporting roller and feeding roller in unison, as and for the purposespecified.
